Hammond had on Sunday described Iran’s nuclear energy program as directed toward making a nuclear bomb.

Mehmanparast said Hammond's comments only reveal the anger of the UK government at Tehran’s progress.

He noted that such remarks indicate that London’s all-out efforts to block Iran’s path to development and prosperity have failed.

Mehmanparast went on to say that such outrageous comments prove that British officials are ignorant of accepted international mechanisms, such as the nuclear Non-Proliferation Treaty (NPT).

The Iranian official emphasized that the Iranian nation will not back away from its inalienable right to a peaceful nuclear energy program under the NPT.

The United States, Israel and some of their allies accuse Iran of pursuing non-civilian objectives in its nuclear energy program.

Iran rejects the allegations, arguing that as a signatory to the NPT and a member of the International Atomic Energy Agency, it is entitled to develop and acquire nuclear technology for peaceful purposes.
